BD33GA5VEFJ-ME2

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The BD33GA5VEFJ-ME2 is a single-output low-dropout (LDO) linear regulator manufactured by ROHM Semiconductor. It provides a fixed 3.3V output with a maximum current of 0.5A. The device operates within an input voltage range of 4.5V to 14V and supports ceramic capacitors for stability. Key electrical parameters include ±1.0% output voltage accuracy at 25°C, typical dropout voltage of 0.6V at full load, and quiescent current of 0.6mA. It features thermal shutdown, overcurrent protection, and a shutdown function reducing standby current to 0µA.
